Oneofthedonormares iocom�tion.arasiticdisease of livestock is costly to theagnculture industry. It is estimated that losses resulling from nematode infections of beefand dairvcattlein the United States alone will reaCh the S600 millionmark by the end of the decade. Farmers try to prevent losses by adminil>tering anthelmintic drugs, which ure expensive, and through pasturerotation.which is labor intensive. An added problem is that some para'ite populationsareresistant to a numberofcommonlyusedanthelmintics.
Researchers, in the field and in the laboratory, have beenstudyingmeans ofcontrolling paTasiteinfections for many years. Now, with the advent ofpowerful computers. thesestudieshave taken on anadded d1meosion.Computerscan be used to develop mathematical models which can examine different means of parasite control."'We can use mathematical models of parasite population biologyto see how the diSease status of the infected livestock alters in time and�pace,..explained Dr.GarySmath, assistant professor of population biology and epidemiology at the Umversity of Pennsylvania School of Veterinary Medicine.''Such modelsalso allow us to examinedifferent strategi� for parasitecontrolbefore they are tested in the field."
Or. Stn.ilh pointedout that the modelingtechnique is thesame whether theresearcher is dealingwuh macroparasites(roundworms. tapeworms,Dukes) or microparasites(viruses, bacteria, protozoa). "Inthe caseof parasiticdiseasecaused byworms, we con::.trutt an<.-quation foreach stage in thelife cycle and simulate the course of mfecuondunng a gnwng season lorspecificclimatic conditions. Weknow thetime neededfor the development ofinfectiouslarvae, how long they can survivein the pasture, and bow long il takes the worm to reach adulthood once ingested. To study the effect of ananthelminticdrug,we can alter the equations to reflectthe drug's action onspecific stages of the parasiteand then determinethe likely reduction in worm burden."
One such study examined different protocols to combat Ostertagwostenagia(stomach worm)anfection mgrazing calves and yearlings inEurope and
temperate regio�in North America. Normally, the infectiOn peaks in August and September and declines oo its own, without drug intervention. "Traditionally farmers used to wrut until the cattle showed sagns of disease before treatingthem with anthelmintic drugs." said Dr.Smith "Such a regimen worksbut requi� repeated administrataon of the drug."Thecomputer modelsimulatedsix protocols: a) no anthelmintic therapy;b) therapeutic administration ofanthelmintic A at thetime of peak infection; c) prophylactiC admintStration of A at three, six. and nine weeks after turnout to pasture: d) movement of calves to a second pasture immediately following a prophylacticdose of anthelminticA: e) prophylactic administration of anthelmintic B three andeight weeks after turnout to pasture; and f) prophylactic admmistrarion of anthelmintLc Cviaan mtraruminal time release dev1ce (bolus), which releaseseffective quantities of the anthelminticfor 80to 100 days.
The model generated information demonstrating the impact of the variousprotocols on theworm burden in the cattle. All the prophylactic prmocals (cto f) significantly reduced the worm burden at midsummer. Dr. Smith pointed out that these protocols work by reducing the number of infectious tarvae in the pasture."The model allows u1. to studyan approach indetail without doing a fieldstudy,"he said."lt allows us to thinlcabout different approaches and examine the problemin depth prior to embarking on a field study."Themodel did not examme the costs ottreatment and the financial return realized by the use of each of the different orotocnl�
Resistance to drugsisa bigproblem in parasite control. Drug �tStance1S hJghCl>t where long-term routine dosage is practiced,"said Dr.Smith...Resistance typically appea� within ten to 50 generationsof the routine application of a drug.�It appearsthat parasites are always onestep abead ofthe drug companaes. Resistance is a vexing problem for horse owners.as seven out of ten of the small strongyles have demonstrated drug resistance. Australian sheep farmers also have tremendousdifficultieswith drugresistant sheep nematodes. which reducethe yitld of wooland meat!iignificantly. It lS important to slow down the spread of such resistant sarains, and
mathematical models can help. "We suspect that within each parasite population there may be individuals which are wholly resistant. not resistant. and panty resistant. If we assumethat the wholly resistant and thenon-resistant strainsare homozygous for the trait and that the partly reststant strain is heterozygous, we can develop a model lor each ofthese populations and can investigate when resistance is likely to appear."The model then can be usedto determinethe most efficient method of utiliLing a drug v.ithout encouraging the rapid�pread of resistant �trains.
Dr. Smith pomted out that parasite populations are regulated by a number of naturalprocesses. "For example.cattle will develop a natural immuoaty during each grazing season.and this causesa decrease1n the worm burden later in the season."Dr.Smith is incorporating these natural regulatory processes an his models sincethey influence drug strategies."The natural regulatory processesrender the host-parasite system more or les!> refractory to perturbation, and so theytendto oppose theeffectsof anlhelminnc!>.�
t·" fm..ahem !i�al modtl�.:.:�n cJucLth-. ..�...ber of field test:. and makethese more etficient.�uch models also reducethenumber of animals neededfor field !>tudies. thou&h they will not entirely eliminate theneed to use animalsin such studies...The model freesthe researcherfromtheneed to think about three or four things at once. Eachvariable and itsimpact can be examined methodically in a controlledSituation without using animals. In essence, a model can be a rehearsal for a field study with animals, making the field studymuch more efficient."
Mathematical models can abo be used to examine vaccmauon strategies prior to field testing. For example, it is possible to determine the number of vaccinated animals neededto halt the spread of an infectiousdisease such � rabies.
The economic benefitsof a given strategy can also be examinedusing models."'We hope to be able to estimate the expected return from specific protocols and so assess the specific wonh of veterinary intervention together witb therisksinvolved."Dr. Smith is collaborating with Dr. Davtd Galligan in the development ofsuch a modeL
